John 6:54 King James Version (KJV)
54 Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
This scripture corresponse perfectly with the following scriptures:
Matthew 26:26-28 King James Version (KJV)
26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples,
and said, Take, eat; this is my body.
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
Communion or Sacrament was given to us as a commandment by Jesus to remember what Jesus has done for us. It is through this communion or Sacrament that we metaphorically partake of his body and his blood. It is a perfect doctrine.
The Catholics went overboard and started to tell us that during the Sacrament the bread and wine actually turn into the body and blood of Jesus. That of course is out of line.
Poor comprehension of God's Word promoted as keen insight you say? LOL
John 6:54 is about faith in Christ (the Lamb of God) not the Lord's supper.
The Gospel of John does not even record the last supper.
Partaking of bread and wine in remembrance of Christ and in doing so, showing His death, is biblical. To teach others that Christ is literally (or metophorically) in physical bread and wine and that by eating and drinking that bread and wine the partaker will attain salvation is not biblical.
Partaking in the Lord's supper cannot save. It is an outward display of faith that is done in remembrance of Christ. It has no power to save. If your church is promoting recieving salvation through participating in the Lord's supper then your church and any other church doing this is performing a vain ritual and teaching a lie.
John 1:29
The next day John seeth Jesus coming unto him, and saith,
Behold the Lamb of God, which taketh away the sin of the world.
Hebrews 9:25-28
Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
26For then must he often have suffered since the foundation of the world: but now once in the end of the world hath
he appeared to put away sin by the sacrifice of himself.
27And as it is appointed unto men once to die, but after this the judgment:
28So
Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
1 Peter 1:18-21
Forasmuch as ye know that ye were
not redeemed with corruptible things,
as silver and gold, from your vain conversation
received by tradition from your fathers;
19But with the precious blood of Christ, as of a lamb without blemish and without spot:
20Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
21Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.
Romans 3:21-26
But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
22Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
23For all have sinned, and come short of the glory of God;
24Being justified freely by his grace through the redemption that is in Christ Jesus:
25Whom God hath set forth to be a propitiation through faith in his blood,
to declare his righteousness for the remission of sins that are past, through the forbearance of God;
26To declare,
I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
Matthew 4:4
But he answered and said,
It is written,
Man shall not live by bread alone,
but by every word that proceedeth out of the mouth of God.
